Ligh.ng: Good
¤ Light sensi.ve materials on exhibit are regularly rotated
¤ Records are kept on light exposure for materials placed on exhibi.on
¤ A schedule is in place for tes.ng and replacement of ultraviolet filtering film
¤ Light sensi.ve materials are not leo out in work areas for extended periods of .me
Ligh.ng: Beeer
¤ Light meters are owned by the ins.tu.on and light levels are checked regularly

Pest Management: GeTng Started
¤ Storage areas and furniture are cleaned on a regular basis
¤ All trash containing food is removed from the building on a daily basis
¤ Staff keeps food in air.ght containers and cleans all ea.ng areas daily

Pest Management: GeTng Started
¤ All incoming items are examined for pest and mold infesta.ons. Remedial ac.on is taken to prevent the spread to the rest of the collec.on.
¤ Any items exhibi.ng signs of pests are isolated from the rest of the collec.on un.l treated
“Bookworm Damage on Errata Page” Bu Ragesoss, http://en.wikipedia.org/wiki/File:Bookworm_damage_on_Errata_page.jpg
Pest Management: Good
¤ Vulnerabili.es for an infesta.on are mi.gated, such as sealing possible infiltra.on areas, use of outside ligh.ng, correc.on of draining problems, sweeping gasket on exterior doors, and use of screens
¤ Storage and exhibi.on areas are monitored for the presence of pests with glue boards

Pest Management: Good
¤ All pests are iden.fied and records are kept about loca.on, number found, as well as records of special events that might affect environmental condi.ons, such as recep.ons, leaks, systems failures etc.
¤ The ins.tu.on’s selected pest management company understands the specific pest control needs for safety of staff, visitors, and the collec.on. No insec.cides are used consistently as a pest deterrent
¤ Advice is sought from a conservator before trea.ng any affected materials
http://ellencarrlee.wordpress.com/2009/03/19/integrated-pest-management-made-easy/
Pest Management: Beeer
¤ Instruc.ons for cleaning storage and exhibi.on areas are wrieen and followed
¤ An formalized integrated pest management program is in place for monitoring and responding to an infesta.on

IPM
“Preserva.on professionals increasingly recommend a strategy called integrated pest management (IMP). This approach relies primarily on non-‐chemical means (such as controlling climate, food sources, and building entry points) to prevent and manage pest infesta;on. Chemical treatments are used only in a crisis situa.on threatening rapid losses or when pests fail to succumb to more conserva.ve methods.”

Principles of IPM
¨ Preven.on ¤ Take necessary measures to
prevent the need to use chemical extermina.on n Facili.es, Environment, Housekeeping
¨ Early Detec.on ¤ Consistent monitoring and
inspec.on
¨ Elimina.on ¤ Take necessary ac.ons to
eliminate pests, preferably through non-‐chemical means http://nature.berkeley.edu/upmc/insectlist.php
Pest Management: Beeer
¤ Selec.on of pest infesta.on treatments, traps, and bailing are appropriate for the safety of collec.ons and people
¤ A specialist in integrated pest management programs for cultural ins.tu.ons review the IPM program at regular intervals
¤ A separate space is available for segrega.on of infested materials or those suspected of infesta.on
